VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 271,524, dated January 30, 1883.

Application filed December 20, 1882.

To all whom it may concern Be it known that I, LOUIS SCHMETZER, a subject of the Kingdom of Bavaria, and a resident of the city of Rothenburg-on-the-Tauber, in the Kingdom of Bavaria, German Empire, have invented certain new and useful Improvements in Velocipedes, of which the following is a specification.

This invention relates to certain improvements in the construction ofvelocipedes, whereby the seat and its supporting-spring can be vertically adjusted so as to enable persons of different age and with limbs of different lengths to use the same size of velocipede. The constructions heretofore used for this purpose were complicated andimpracticable, for the reason that the adjustment of the seat required too much time, and that the connecting parts were slotted, and thereby weakened, so that the whole arrangement was shaky, and did not possess that degree of simplicity and solidity which is absolutely necessary for a device that is propelled at such a high degree of speed.

The invention consists of a velocipede provided with means whereby the seat-supporting spring is vertically adjusted along the main 'and auxiliary stays, as will more fully appear hereinafter.

In the accompanyingdrawings, Figure 1 represents a side elevation, partly in section, of a velocipede with myimproved adjustable seat. Fig. 2 is a'modih'ed construction of the connection of the seat-supporting spring with the stays of the elocipede; and Figs. 3, 4, and 5 are detail horizontal sections, showing the connection of the spring with the auxiliary stay.

Similar letters of reference indicate corresponding parts.

I) in the drawings represents the main stay; (I, the auxiliary stay, which latter is inclined. A portion of the main stay I) has an inclination corresponding to that of the auxiliary stay a, so as to serve, together with the stay a, for the vertical adjustment of the seat supporting springd,which retainstherebyits horizontal position. The vertical adjustment of the spring and seat increases or decreases the distance between the driving crank-axle and the seat, and enables thereby persons of different age (No model.)

and with limbs of different lengths to use the same velocipede. The spring (Z is fastened to the auxiliary stay a by means of a sleeve, f, as shown in Fig. 3. The ends 9 of this sleeve are made to clamp the end of the spring at, which end is bent at right angles to the body of the spring. One end of the sleeve fhas a smooth, round hole, while the other end has a smaller threaded hole, through which holes a screw-bolt, i, is passed, that is securely retained by a nut, h, applied to the threaded end of the screw-bolt i. The spring dis tightly clamped by the screw 2' and nut h between the ends of the sleeve f, and readily adjusted higheror lower on the main and auxiliary stays Z) and a by first loosening the screw 6 and afterward tightening the same.

Instead of clamping the end of the spring d between the ends of the sleeve fby means of the screw 17, the spring (1 can also be fastened by being riveted to the elongated end 9 of the sleeve f, as shown in Fig. 4E. The ends 9 g of the sleeve fare clamped to the stay a by the screw 1 which is provided with thumb nuts.

In order to lessen the vibration of the spring (I, the sleeve f is lined with a thick rubber sleeve, m. A second modification of this arrangement is shown in Figs. 2 and 5; but in this case the auxiliary stay a is made flat, and is provided with projecting studs 0 at both sides. The spring dis forked at its upper end, so as to engage the stay a, one half, 0", of the fork being formed by bending the end of the spring d at right angles to its body, as shown in Fig. 5, while the second half, .9, is pivoted by its enlarged horizontal portion to the spring 61,130 which it can be tirinly fastened by the clamping-screw t, which passes through a slot of said enlarged portion. Both parts 1" and s of the fork are provided with holes which correspond to the projecting studs 0 of the stay a. By loosening the screw t the movable portion 8 can be released, and can be brought in the position shown by dotted lines in Fig. 5, so that the spring can then be set higher or lower, as required. In order to diminish the vibration of the seatin this arrangement,theprojections 0 are also provided with rubber rings. In both cases the lower U-shaped end of the spring cl moves readily along the main stay I), to which it can be fastened, if desired, by a clampingsleeve in the same manner as the upper end of the spring is applied to the auxiliary stay a.

The seat (1 is securely attached to the horizontal portion of the spring (I, and preferably covered with a rubber plate containing pert'orations for the purpose of keeping the seat cool. If desired, ahollow rubber cushion filled with air or water may be used, by which an agreeable, cool, and comfortable seat is obtained and the vibration in riding diminished. Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In velocipedes, the oombination,with the main and auxiliary stays, of a seat-supporting spring and means whereby the upper end or the upper and lower ends of the spring may LOUIS. SGHMETZER.
